I recently noticed a lump on my Nigerian Dwarf doe (3 yrs old). It's in her upper flank, right behind her floating rib (about 6-7 inches down from her spine). It's about the size of a half walnut I'd say, though it's hard to tell. It's completely under the surface, not at all attached to the skin. It is firm, but not rock hard. I can poke at it and it doesn't seem too painful to her, but she notices if I do it too much. A picture would do no good, as you cannot see it, only feel it. There is no surface trauma at all. I got immediately worried about CL, but she comes from a reputable breeder, and it is certainly not at all in an abscess stage. But I'm wondering what else it could be? A hernia? It doesn't seem like a place she would have had an injection, but maybe I'm wrong. She also might be pregnant (due in august), but i don't know if that means anything. She only lives with her daughter, who is still small, so I doubt it could be a butting injury. It seems to have remained about the same size since i started monitoring it a few days ago. Any ideas would be much appreciated, thanks, I'm quite concerned!
